As against close end questions the open-end questions do not contain any prompts and are designed for unformalised
That, though, is not the end of the matter, for, as I have sought to point out elsewhere, (38) an especial problem which may attach to unformalised
relationships is the determination of when they begin and, more particularly, when they end.
In his analysis of the frustratingly unformalised obsidian assemblages from sites in the Reefs/Santa Cruz Islands that date to the time of Lapita style pottery, Sheppard (1993) made an important breakthrough that helps explain this seeming anomaly and can direct us toward useful methodological pathways.
The history of research on obsidian in the Willaumez Peninsula demonstrates that even seemingly simple and unformalised artefacts can open up windows into past social processes.
Of course, a few dissenting voices, from Milton Friedman's (1949) classical paper on the Marshallian demand curve to the more recent contributions by Michel De Vroey (1999a, 1999b, 1999c) on the Marshall-Walras divide, have tried to contrast the prevailing reductionist trend from different perspectives; yet, being chiefly unformalised
and methodologically oriented, these papers have not succeeded in breaking the analytical scaffolding erected by Hicks and thereafter accepted by theorists and historians alike.
Unmarried couples already have enough to put up with, not least the ignominy of fewer legal rights or dealing with snooty doctors who don't recognise unformalised
unions, all for the sake of a little scrap of official paper.
Mills (1959), typified exploratory studies as "probing new substantive or methodological areas, which may rest on still unformalised
and unintegrated theoretical, hypothetical, and methodological arguments".
